CA N O P E N E R SPECIFICATION forming part of Letters Patent No.536,005, dated March 19, 1895. Application filed June 16,1894. SerialNo. 514,763. (No model.)

- of sheet metal swaged into form, thereby producing the same at a smallcost, and at the same time to give the metal such form as to produce avery strong and efficient article.

In the accompanyingdrawings: Figure 1 is a perspective view of my canopener showing its front end and top. Fig. 2 is a perspective view ofthe same showing its under side, and Fig. 3 is a plan view of the blankfrom which said can opener is formed.

The metal is first cut out by means ofvsuitable dies from sheet steel inthe form shown in Fig. 3. It is then struck by means of swaging dies tochange it from the form shown in Fig. 3 to substantially that shown inFigs. 1 and 2. 7 After thus forming the metal into its proper concaveand trough shaped form, a slot'or recess is made, as indicated by thebroken lines in Fig. 3, to divide the upper forward end 5 of the canopener from the knife portion 6, and the edge of said knife portionalong the line of the slot is properly beveled to complete the device.The forward end 5 is made hollow or trough shaped with a dependentflange at each edge and in alignment with the hollow or trough shapedhandle 7, while the knife 6 is dependent from one of the flanges of saidconcave forward end and one of the under edges of the handle. In useafter puncturing the can near one side with the point of the knife 6,the forward end dependent flanges fit over the rim of the can andprevent the opener from Working either to the right or left. The concavetrough Shape of the handle also gives it great strength while by makingthe forward end and handle in alignment with each other as one.continuous trough I get a square lift on the fulcrum and avoid all weakplaces or offsets .at the junction of said handle and forward end.

I am aware that Patent No. 224,022, of February 3, 1880, shows anddescribes a can opener having a handle with a knife in alignmenttherewith and in the same plane, a flat fulcrum or forward end'offsetfrom said handle and knife and standing at right angles thereto and aguiding lip dependent from the fulcrum end of that edge which isopposite the knife, all formed in one piece of sheet metal, and I herebydisclaim the same. In said can opener each of the aforesaid parts Wereleft in their original flat form.

I claim as my invention The herein described sheet metal can openerhaving the concave trough shaped forward end 5, the concave troughshaped handle 7 in alignment with said forward end as one continuoustrough, and the knife 6 dependent from said forward end and one of theunder edges of said handle, substantially as described and for thepurpose specified.

CHARLES E. ANDREWS.
